David Vitter, American lawyer and politician
David Bruce Vitter (born May 3, 1961) is an American lobbyist, lawyer, and politician who served as United States Senator for Louisiana from 2005 to 2017.

A Republican, Vitter served in the Louisiana House of Representatives from 1992 to 1999. He then represented Louisiana's 1st congressional district in the U.S. House of Representatives from 1999 to 2005.

Vitter was first elected to the U.S. Senate in 2004. He was the first Republican to represent Louisiana in the Senate since the Reconstruction Era, and the first ever Republican to be popularly elected. In 2007, Vitter admitted to and apologized for past involvement with a Washington, D.C. escort service. In 2010, Vitter won a second Senate term by defeating Democratic U.S. Representative Charlie Melançon.

Vitter unsuccessfully ran for governor to succeed the term-limited Bobby Jindal in the 2015 gubernatorial election. He lost the general election to Democrat John Bel Edwards. While conceding defeat to Edwards, Vitter announced that he would not seek reelection to his Senate seat in 2016 and would retire from office at the completion of his term. Following the conclusion of his second Senate term, Vitter became a lobbyist.
